Prefabricated Housing Production Line

The prefabricated housing production line is used for the industrial production of concrete prefabricated components (PC components) or modular buildings for construction, and is widely applied in the field of prefabricated construction.

I. Core Functions and Product Types

The prefabricated housing production line encompasses multiple functional areas, including steel bar processing, concrete mixing, and assembly-line production. It achieves factory-based and large-scale production through digital and information technologies. Its core products include PC components such as composite floor slabs, beams, and columns, as well as modular building units. Modular construction involves breaking down a building into independent modules, which are manufactured in a factory with integrated structural, mechanical, electrical, interior, and exterior finishes, and then transported to the construction site for assembly. The annual delivery capacity can reach 20,000 to 30,000 modules.

II. Technological Development and Corporate Practices

Domestic companies have made early布局 (early布局 can be translated as 'early strategic布局' or simply 'early investments') in this field, with significant technological iterations. For example, China Construction Machinery Co., Ltd. took the lead in research and development, undergoing three generations of technological upgrades to form a mature system. Northern Heavy Industries Group Co., Ltd. has achieved localization of automated production lines with an annual output of 1 million square meters or more since 2013, breaking the bottleneck of reliance on imported key equipment. As of June 2026, the intelligent construction-MiC technology independently developed by China Construction HaiLong has been implemented in 137 projects across 15 provinces and 24 cities nationwide, covering scenarios such as affordable housing, urban renewal, campuses, hospitals, and hotels, with a cumulative construction area of 6.12 million square meters.

III. Comparative Advantages Over Traditional Processes

1. Construction Period and Quality: The factory assembly line achieves millimeter-level precision control, significantly enhancing building performance in terms of waterproofing, sound insulation, and earthquake resistance. The construction period is shortened by more than 30% compared to traditional processes.
2. Environmental Protection and Maintenance: The production process reduces dust and noise pollution. Modules can be disassembled, stacked, and flexibly expanded, with a reuse rate exceeding 90%, lowering the full lifecycle maintenance costs.
3. Scalability Benefits: Through standardized design and industrial production, project costs are reduced by 15%-20%, making it suitable for large-scale affordable housing and other livelihood projects.

IV. Application Scenarios and Market Prospects

This technology has expanded from residential applications to public buildings, such as hospitals and schools, which have high requirements for construction efficiency and quality. With the advancement of the 'dual carbon' goals, prefabricated construction has become an industry transformation direction due to its energy-saving and emission-reduction advantages. It is expected that the market size will maintain an average annual growth rate of over 15% in the next five years.
